The philosophy of logic is a posterior science, which examines the philosophical principles of logic as well as the matters derived from the logical debates. Aristotle's philosophy of logic has not been collected yet, but we need to do it due to comparing the ancient logic with the modern interpretations. For gathering these philosophical principles we have to refer to Aristotle's own works directly. Perhaps the most important transition which was occurred in Aristotelian logic was formed by the Muslim scientists like as Ibn-Sina and his remarkable work al-Isharat wa-'l-tanbihat (Remarks and Admonitions). The writer of this paper believes that the so-called transformation not only happened in the formal division of logic by the Muslim philosophers, but they had an essential and profound viewpoint to logic too. We can find the origin of these progressions in the work of the Neoplatonist Porphyry, known as the Isagoge (Introduction), which was appended to the beginning of the Organon series as an introduction to the study of the Categories; however it finally removed categories and made the syllogisms formal. Demonstrating such a theory requires knowing Aristotle's logic exactly. The present paper deals with the Prior Analytics, which contains the theory of syllogism as well.
